问题 I'm writing a GUI for using the oracle exp/imp commands and starting sql-scripts through sqlplus. The subprocess class makes it easy to launch the commands, but I need some additional functionality.

问题 I have created a table with Blob datatype but I do not know how to insert values into the table or view the table content using SQL*Plus. Please help me. 回答1: It depends on what kind of data you want put into a BLOB.
